DFG’S BOB Coil E is the first and only extra heavy duty electrical coil punch and binding machine in its class. It can punch world record 30 sheets (20#, double D oval hole) or 3 mm hardboard in one punch. This is due to DFG’s Hi-Torq™ punch motor and innovative super strength machine design. With DFG’s SERVOGROVE™ Roller Binding System, it binds small or larger books (up to 22 mm) effortlessly. Lager size coil is not difficult with some practice. BOB Coil E can punch and bind any length and thickness of book.

All Electric Operation: Extra Heavy Duty Electrical Coil Punching and Coil Binding with the simple press of a foot pedal.

Punches a double “D” oval hole (4x5mm hole) which increases the binding speed and makes it easier to bind thicker books. DFG double “D” oval hole is a True .250” pitch. This is important because plastic coil construction is .250” pitch and this makes it faster and easier to drive the coils into the book. With fully dis-engagable punch pin design, 0.250” pitch is far superior to 0.248” pitch. It makes books stronger and tolerant of paper size fluctuation, which is very common in today’s digital printing (letter size sheets 8.5”x11” cut from 12” x 18” sheets). DFG only uses 0.248” pitch for low cost coil machines that don’t have dis-engagable punch pin design.

For any length and thickness book: Punch any length of paper with our open throat die and alignment pin. DFG’s design makes it possible to punch paper of any length with no restrictions. Whatever your paper length is, you can punch it on the BOB Coil E. After the first punch, put one hole through the alignment pin to keep your subsequent punches aligned correctly and punch again. You will have perfect alignment for the full length of paper.

High Volume Punch Capacity: With our specially designed Hi-Torq™ punch motor, DFG torture tested it for 200,000 trouble free punch cycles. The BOB Coil E can punch 30 sheets of 20 lb paper or 3mm (1/8” thick) hardboard covers with the gentle push on the foot pedal. No other table top punch and bind machine in its class can accomplish this task.

Super Strength Punch Mechanism: Cast-hardened & heat-treated precision steel punch pins provide superior strength & hardness. You add DFG’s lubrication system, and that drastically reduces friction and punch pin wear. This equates to longer machine life and a sharp clean perforation every time for the end user. High-Speed, commercial punches that cost over $30,000 lubricate their punch pins. DFG utilizes this technology in our commitment to taking the extra step to deliver the best machine possible to the market place.

Heavy duty Chassis: Countless years of experience has led DFG to produce a machine with the most sophisticated design, testing methods, and manufacturing techniques to develop the most rigid heavy duty chassis in its class at 29% less overall machine weight.

New Patent Pending SERVOGROVE ™ Roller Binding System: This new roller system binds small or larger books (up to 22 mm) effortlessly. Absolutely no costly separate coil inserter needed. Manually binds any size book. The SERVOGROVE ™ Roller Binding System dramatically increase binding speed, when compared against smooth roller systems by 50%. Once the coil is started, simply lay the book against the grooved roller. The coil is easily inserted into the book, making this inserter one of the easiest-to-use. Top-mounted roller position will give the operator greater control, improve their efficiency, and have less operator fatigue, which improves production. A foot-pedal activates the roller and is compatible with plastic & metal coils.

Full Die Disengagement Pins: Utilizing the DFG’s World’s First full disengagement-pin design for coil binding machines (recently copied by other manufacturers), our punched paper is free from partial punches, on any size project. Our disengagement-pin design uses independent coil spring mechanisms on each pull pin that allows the pins to disengage with a crisp snapping action. Our punch pins are heat treated and precisely ground to ensure consistent, clean, punching.

J-Shaped Book Pre-former Guide: It is essential when binding thicker books (1/4” or thicker) to have the ability to form the book to the proper radius of the Coil. This is why DFG has developed the J-Shaped Book Pre-former Guide as opposed to utilizing U shaped pre-former. The J-shaped Book Pre-former Guide supports the book better than a U shape guide because it supports the back of the book better. This solves book buckling and will assist the operator to properly shape the book’s spine, for faster & easier coil insertion. The J-shaped pre-former concept is widely used in larger, automatic binding machines.

Side Margin Control: Allows you to evenly center your punch pattern on your sheet.
Punching Margin Control: Provides the correct punch depth for each coil size. This will maximize the book's tear resistance

Rugged Die Cast Metal Construction: The BOB Coil E is made of DFG precision engineered die-casting base and side plates rather than low-cost, flexible sheet metal like some other machines in its class. DFG uses die casted metal for the base and sides of the housing unit to insure your machine is solid in all the important places which significantly improves machine life as compared to sheet metal base construction. Any base deflection can shorten the life of the machine

DFG’S BOB Coil M is an extra heavy duty manual coil punch and power binding machine. It can punch up to 25 sheets (20#, double D oval hole) or 3 mm hardboard in one punch, if you have a strong arm. With DFG’s SERVOGROVE™ Roller Binding System, it binds small or larger books (up to 22 mm) effortlessly. Lager size coil is not difficult with some practice.

DFG’S BOB Comb E is the first and only extra heavy duty electrical comb punch and manual binding machine at its class. It can punch world record 35 sheets (20#) or 3.2 mm hardboard in one punch. This is due to DFG’s Hi-Torq™ punch motor and innovative super strength machine design. BOB Comb E can punch and bind any length and thickness of book.

Made of sturdy die-casted metal rather than flexible sheet metal, the BOB COMB E is the most heavy duty, reliable, user-friendly, and functional machine in its class. DFG chose to use die-casted metal for the base and sides of the housing unit rather than using sheet metal for the punching surface to ensure your machine is solid in all the important places.

The BOB Comb E uses an encased lubrication system that drastically reduces friction and punch pin wear, which equates to longer machine life for the end user. High-speed, commercial punches that cost over $30,000 lubricate their punch pins. DFG utilizes this technology in our commitment to taking the extra step to deliver the best machine possible to the marketplace.

Punch any length paper with our open throat and alignment pin. Our design makes it possible to punch paper of any length with no restrictions. After the first punch, put one hole through the alignment pin to keep your subsequent punches aligned correctly.

With our specially designed Hi-Torq™ punch motor, torture tested for 200,000 cycles, the BOB Comb E takes comb binding to the next level of convenience and ease. BOB Comb E can punch 35 sheets of 20 lb paper with the gentle push on a foot pedal, eliminating the manual punching strain on staff members. Our high punching capacity of 35 sheets gives you 40% more productivity over machines that punch only 25 sheets.

After punching your paper, place the comb on the comb opener teeth and use the handle to open the comb, which easily open with the slightest of pressure.
